The vagina is supplied blood from the vagina artery. This artery is found only in females. The internal iliac artery branches off to create the vagina artery in women. The vaginal artery is said to come from either the uterine artery or the internal iliac artery. In the Terminologia Anatomica terms, the blood that comes from the vaginal branches of the uterine artery is actually describing the blood coming from the uterine artery, not from the internal iliac artery. In males, the inferior vesical artery may be compared or assumed to be the same as the vaginal artery in females. There are frequently two to three branches of the vaginal artery that present in a woman. This varies per individual. The vaginal artery is a part of the cardiovascular system, and supplies the vagina, some parts of the bladder including the base, and the rectum. The structure of the vagina artery supplies the mucous membrane of the vagina. This can also branch into the fundus, vestibule, and parts of the rectum.
